Several hypotheses derived from an information sampling model of group discussion were tested with 3-person teams of physicians given 2 hypothetical medical cases to diagnose. Some of the information about each case was given to all 3 team members before discussion (shared information), whereas the rest was divided among them (unshared information). As predicted, shared information was, overall, more likely to be discussed than unshared information, and it was brought into discussion earlier. In addition, it was found that team leaders repeated substantially more case information than did other members and that, over time, they repeated unshared information at a steadily increasing rate. The latter findings are interpreted as evidence of leaders' information management role in problem-solving discussions.
从群体讨论的信息抽样模型中得出的几个假设，在由三名医生组成的团队中进行了测试，这些团队要诊断两个假设的医疗案例。每个案例的一些信息在讨论前提供给了所有三名团队成员（共享信息），而其余信息则在他们之间分配（非共享信息）。正如预测的那样，总体而言，共享信息比非共享信息更有可能被讨论，并且更早被引入讨论。此外，研究发现团队领导者重复的案例信息比其他成员多得多，而且随着时间的推移，他们重复非共享信息的速度稳步增加。后一项发现被解释为领导者在解决问题讨论中的信息管理作用的证据。
